- imum amount of juice will be obtained from the fruit or other objects with but a minimum effort.

Further, the invention provides a hand' press or juice extractor which is particularly adapted for extracting the juice from citrus fruit halves and which is so constructed as to flatten out the fruit half to effectively press the juice therefrom.

The invention also contemplates a hand press embodying a flmnel or receptacle, whereby the extracted juice may be directed into a container. I

With the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangement of'parts to he hereinafter specifically referred to, claimed and illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective of a juice extractor constructed in accordance with my invention;

Figure 2 is a vertical sectional view of the same illustrating the plunger in elevated'position;

Figure 3 is a similar view showing the plunger in operated position; I

' Figure 4 is a horizontal section taken on the line 4.-4= of Figure 3; and

Figure 5 is an elevation of the removable receptacle embodied in the invention.

Referring to the invention in detail an upstanding arm or bracket 5, formed with an attachingplate 6 at its lower end adapted to be secured to a horizontal support by'removable fastenings 7, is provided. At its upper end the arm is forwardly curved, as at 8, and is point diametrically opposite the forwardly curved end.

To discharge the extracted uice into a suitable receptacle, an elliptical 1n cross section shaped funnel 11 is removably received in the rim or'frame, and is formed with a taperedbottom 12 having a central depending discharge spout 13. At its upper end the funnel is formed with a lateral flange 14: which rests upon the upper end of the rim or frame to removably support the funnel.

For the purpose of holding fruit or other objects .to be pressed, an elliptical in cross section shaped receptacle 15 is received within the funnel 11 and terminates at its upper edge in a lateral flange 16 which rests upon the flange 14. This receptacle is open at the top and is provided with an inclined bottom wall 17 and a longitudinally curved rear wall 18.

To permit the extracted juice to gravitate from the receptacle and into the funnel the rear wall of the'receptacle is formed with a plurality of vertically extending spaced parallel slots 19 communicating at their lowerends with similarly spaced slots 20 provided in the lower edge of the inclined bottom wall.

(lo-operating with the receptacle in pressing'or extracting juice from objects placed therein, is. a hand lever 21, normally lying across the upper end of the receptacle and provided with a right angularly disposed extension 22 received between the cars 10 I and pivotally supported between the same by means of a removable pivot pin 23, the

latter passing through the ears and extenan area slightly less than the cross sectional area of the receptacle, is cast with the lower end of the arm or web and is adapted to be pressed against a fruit half contained in the receptacle by exerting downward pressure on the hand lever. hand lever is formed with a spherical grasping element 28 at its free end. It will be observed that the plunger .or head, when in pressing position, is directly opposed to the bottom wall 17 in parallel relation thereto.

.Thus, due to the fact that the entire working surface of the plunger or head is parallel For this purpose the to this bottom wall, the entire surface of the fruit half will beJ'subjected to the pressure of the bottom wall and plunger. To maintain the interior parts ma sanitary condition, an elliptical shaped closure plate 29 is attached to the under face of the lever 21 adjacent its pivoted end. and overlies the open end of the receptacle to close.

' the latter, as illustrated in Figure 1.

therebeneath. It will be observed that the -will pass from the device.

several elements embodiedin the invention may be readily disassembled for cleansing purposes, and thus the entire device may be maintained in a clean and sanitary condition at all times. i

Due to the fact that a pressed citrus half assumes an elliptical configuration in plan and that the plunger 27 follows the curvature of the curved wall 18, the fruit half will be forced forwardly so that its forward edges are held against-the curved wall 18. With the fruit pressed in this manner substantially all of its pulp will be trapped within the fruit skin. It will, therefore,'be seen that substantially none of the solid particles g It will also be observed that as the fruit half is pressed it sweeps the slotted rear wall of the receptacle to maintain the slots therein clear at all times. It will, therefore, be apparent that any pulp that may escape from the fruit skin will not be sheared off by the plunger to clog the slots.

One half or a portion of an orange or other citrus fruit is placed in the receptacle 15, with the exposed pulp held against the slots 19 in the wall of the receptacle 15. This slotted wall is curved both longitudinallyand transversely; in the particular illustration of the drawings the, wall is curved longitudinally and vertically, but the term transversely is employed to indicate a curvature at rlght angles to the longitudinal plane of -the wall or receptacle.

The plunger 27 which swings on the axis 23 is moved against the fruit, and this movement of the plunger not only squeezes or compresses the fruit but, because of the changing angle of the lower end crime of the plunger relative to the abutment wall 17 exerts a forward extruding or pressure action on the fruit, thus pressing the pulpy face of the fruit and edge or the rind or skin against the curved slotted wall so as to squeeze out the juice and wipe the small portions of ulp along the slots and through the slots to eep the slots always free and open.

Asthe plunger reaches the completion of its compression movement it compresses the fruit so as to confine the pits and major portion of the pulp in the skin. When the squeezing operation is ended the skin and pulp can be removed and there will be practically no pits orpulp-left in the receptacle.

There are three essential-s in the operation of the device: There must be an abutment wall against which the fruit is pressed by the plunger; there must be a slotted wall curved in two directions, which conforms to the shape of the edge of the squeezed half of the fruit, and there must be a changing angle to the movement of the plunger to press the fruit against the slotted wall as the.

fruit is squeezed, and to ultimately compress the edges of the fruit so as to confine the pits and major portion of the pulp therein. This changing angle is due to the swing of the plunger on its axis, as clearly illustrated in the drawing. The wiping action of the pulp in the slots keeps the slots open and clear.

What is claimed is:

1. In a "press an elliptical in plan receptacle, one side wall of which having 'a downwardly and inwardly curved portion which extends a considerable distance below the opposed side wall, a flat bottom wall connecting the lower edge of said opposed wall and lower wall portion in exerting both radial and thrust pressure on the contents of the recep tacle.

2. In a press a vertical post, a laterally extending supporting member attached thereto, an elliptical in plan receptacle carried by the supporting member, one side wall of the receptacle having a downwardly and inwardly curved portion which extends a considerable distance below the opposed side wall of the receptacle, a flat bottom wall connecting the lower edge of said opposed wall and the lower edge of-the curved .wall portion and-located at an oblique angle with re spect to the horizontal, a lever pivoted to the supporting member, a plunger carried by the. lever and movable in the receptacle, and a cover plate attached' to the lever directly above the plunger and normally resting upon the upper edge of the support to close the receptacle. v

3. In a press an elliptical in plan receptacle, one side wall of which having a downwardly and inwardly curved portion which extends a considerable distance below the side wall, a flat bottom wall connecting the lower edge of said opposed wall and lower edge of the curved wall portion and located at an oblique angle with respect to the horizontal, the curved ,wall portion having vertically extending parallel slots and the forward edge of the inclined bottom being also provided with parallel slots which communicate with the lower ends of the vertically extending slots, and a plunger in the receptacle and 5 co-operating with the flat bottom and curved wall portion in exerting both radial and thrust pressure on the contents of the receptacle.

4. A press comprising a wall curved longilo tudinally and transversely, an abutment wall at an angle to the curved wall, a pivoted plunger. mounted to swing on its axis and move toward and away from the abutment wall, said curved wall having slots therein which are radial to the axis of the plunger, and are open and unobstructed at their lower. ends, said slots being continuous and unbroken and extending away from the lower end of the curved wall.

5. A device of the character described, in-

cluding a wall curved in two directions and having slots therein which are open and unobstructed at their lower ends, and means for forcing a portion of citrus fruit or the like with its pulp exposed face against said slotted wall, said means causing a forward pressing action of the fruit against the wall and a compressing action of the fruit to move the same longitudinally of the slots, said slots being continuous and unbroken and extending 1away from the lower end of the curved wal 6. A device of the character described including an abutment wall, a two-way curved slotted wall adjacent the abutment wall, the

slots in the said Wall being open and unobstructed at their lower ends, a pivoted plunger movable toward'and away from the abutment wall and swinging in the arc of a 40 circle, whereby the angular disposition of the plunger and the abutment wall vary with the movement of the plunger, so that a compressing movement of the plunger against a portion of citrus fruit or the like tends to force the fruit against the curved wall and wipe the face of the fruit along the slots and confine the major. portion of the pulp and pits within the compressed fruit, said slots being continuous and unbroken and extendingi away from the lower end of the curved wa l.
